New laptop DDR3 lamp test instructions

Product synopsis:
This product for a generation notebook DDR3 test lamp upgrade the product, product comprehensive support laptop forward and reverse interface, it is to use leds light and destroy data to indicate the signals of opening address lines with short circuit, instead of traditional using a multimeter measurement method for them one by one, to repair it didn't turn on, don't show, don't read the fault of memory and so on the mainboard, maintenance is an essential tool notebook computer motherboard.
Instructions:
1, with the 3.3 V in tester (CR2032) battery, insert the corresponding notebook motherboard respectively of DDR3 memory each slot, mainboard don't have electricity, the bright and brightness lamp test consistent, signal lines that normal, if has the bright lights or very bright, indicating that this signal have open short-circuit fault, using a multimeter to further define the fault point. (note: all kinds of signals, because tester in each of the contractor the mainboard design and the different chipset, a part of the signal may show that the different, please maintenance personnel using the same motherboard control judge fault.)
2, memory pin the corresponding signal in the list below:
